The Verdigris

“When clean hands must do unclean work, you do not reach for the brightest blade—lest you stain the pristine edge. Instead, you grasp the patinated razor. The weathered tool—known and trusted, surgical and silent.

Let the Verdigris go, and do what the Daughters of the Emperor cannot.”

Overview

The Verdigris, often referred to in whispers as the Sisters of the Tarnished Rose, are a clandestine force operating outside the formal structure of the Ecclesiarchy.

Formed in the aftermath of the Thirteenth Black Crusade and the Siege of Ophelia VII, they were conceived not as a formal Order Militant, but as a field doctrine—a living experiment in rapid, autonomous intervention within the ossified bureaucracy of the Imperium.

Composed primarily of battle-hardened survivors of catastrophic campaigns, Sisters whose entire commanderies were annihilated, the Verdigris begin as those who take the Vow of Verdigris, forsaking the colours and oaths of their former Orders while retaining unwavering devotion to the God-Emperor of Mankind.

In doing so, they pass beyond convent and canon alike, becoming an unsanctioned yet tolerated instrument of Imperial will, a force deployed where politics, faith, or morality render conventional Orders incapable. Their numbers remain unrecorded. Their deeds survive only in fragmented after-action reports, redacted Inquisitorial transcripts, and the scant testimony of those who have fought beside them.

To most of the Imperium, the Verdigris are a rumour at best—yet where the Emperor’s design demands what no other arm may perform, they appear.

"It is said we are His true sons. If that is so, then they are surely His forgotten daughters—

We are His wrath. They are His reckoning.”

Founding

The origins of the Verdigris lie in two concurrent revelations.

In the aftermath of the Cicatrix Maledictum and the loss of Abbess Sabrina, the young Celestian Morvenn Vahl was elevated to the mantle of Abbess Sanctorum of the Adepta Sororitas. The High Lords of Terra, believing her a convenient figurehead, acquiesced to her appointment—expecting she would be easily guided. They gravely misjudged her.

From the outset, Vahl perceived that the Imperium’s greatest weakness was not a lack of faith, but its fractured and adversarial nature. Rivalry between the great branches of the Imperium—Administratum, Mechanicus, and the varied Factions Militaris—crippled Imperial response and magnified the price of every victory through compartmentalization, isolation of intelligence, and the absence of joint command.

At the same time, within the Tower of Hegemony, Captain-General Trajann Valoris and the macro-cogitators of the Custodian High Analytica reached a parallel conclusion. The Imperium possessed no human instrument of absolute loyalty—no force incorruptible by ambition or avarice, capable of acting with surgical precision where transhumans could not.

Among the Sisters of Battle there exists a rite whose details are denied to the public, and which persists only in oral tradition: veterans who survive the destruction of their commanderies, yet could no longer find solace among other Sisters, might undertake a pilgrimage to Holy Terra and petition the Abbess Sanctorum to take the Vow of Verdigris—to pass into rust. This euphemism, long understood as a plea for death without sin, served as the final mercy for those who could no longer bear the weight of survival.

When the first such pilgrims arrived from Ophelia VII, survivors of the devastation wrought by Kol Rakhul, the Night Lord known as the Death of Saints, Vahl reformed the rite into a new doctrine. Rather than granting release, she reframed the vow as a covenant of renewal: those passed over for martyrdom were chosen for a new calling, as faithful executors of the Emperor’s design—achieving His objectives, no matter the price in blood, the enemy’s or their own.

These Sisters were quietly spirited from the Ecclesiarchal Palace into the tutelage of the Eyes of the Emperor, under the oversight of Tribune Decian Thalor, master of the Custodes’ intelligence network. Stripped of name, title, and Order, these women, once shattered by trauma, were reforged through Custodian discipline and divine purpose into the Emperor’s tempered blades—Capable. Fearless. Unbreakable.

Thus the Verdigris was born—a compact of Custodian precision and Sororitas conviction, a mortal instrument of the Emperor’s will, unyielding in faith and purpose.

“Accept that your life before has ended. Where you must go, dogma is death. Become what the Emperor requires of you. And if you must cling to faith as you enter the shadows, let it be only this: He chose you for this task.”

—Verdigris Indoctrination, excerpt attributed to Brother Kalluin of the Oculis Imperatoris

Doctrine

Founded on the belief that the Imperium’s greatest liability lies not in the enemy without, but the fissures within, weakening its very foundation, the Verdigris’ precepts are not a codex of reaction and restraint, but a doctrine of preemption and preservation. It defines their purpose as both an instrument and ideal—the Emperor’s virtue made manifest—unity, duty, and purity—drawn taut as a ligature to arrest discord and excise decay within the body Imperialis until harmony can return.

Where conventional Orders Militant function through ritual, hierarchy, and austerity, the Verdigris deploy as an extension of the Emperor’s will, empowered to take decisive measures where the paralysis of scripture, bureaucracy, or politics might stay another’s hand. Operating without oversight courts the hubris of mistaking one’s will for His—yet they accept this risk as the cost of vigilance. Each mission is sanctified by outcome rather than process. Righteousness lies not in avoidance of the unclean, but in enduring heresy without corruption if it serves to enact His design. To carry the Emperor’s light into darkness is to bear the tarnish of ruthless necessity in silence.

Their combat philosophy rejects static warfare in favour of precision intervention. Verdigris forces are dispatched where the Imperium’s arteries have split—to suture the wound between its sundered institutions—operating as mediators, saboteurs, or executioners according to circumstance. Whether embedded within the Militarum, waging war beside the Astartes, or serving clandestinely under Inquisitorial mandate, they are bound not by allegiance but by alignment to the Emperor’s purpose. They walk the hidden lines between factions—Chapter and Convent, Ordo and Shield-Host—ensuring that when the Great Enemy rises, it will not find the Imperium distracted, dissonant, or unprepared.

The Maxims of the Verdigris do not reject martyrdom outright; they hold that service to the Emperor—not death in His name—is their highest duty. They embrace the blasphemy of strategic autonomy—that His will be done at any price—and accept whatever judgement its outcome brings. Within the Imperium’s labyrinth of divided loyalties, they are the hinge upon which unity may, for a moment, turn.

“Obedience is the virtue of the many; discernment, the burden of the chosen.”

— Excerpt from the Doctrine Verdigris, Maxim IV

Gear

In training the Verdigris are stripped of all that came before, not just in title or allegiance, but in the very steel they wear.

Before taking the Vow of Verdigris, they scour their armour to bare metal—the sacred shell exposed down to the copper-rose gleam of raw ceramite—casting off all symbols, colours, and glory. 

Then, atop the Imperial Palace, in the shadow of the Golden Throne, they step into the rains of Holy Terra and speak their final vows—not baptized in fire, but consecrated by water. 

The patina of their namesake that forms is no mere weathering. It is a memory. It is proof. A living sacrament, so that wherever they go, and whatever they must do, they remember what they fight for. 

I return to my Mother,
Soul and steel laid bare,
I find truth in His shadow,
My duty reforged there.

I cast off name and burden,
God-Emperor’s chosen be,
His will my only purpose,
I go forth, Verdigris.

-  The Vow of Verdigris

Their panoply reflects their unique genesis: a hybridization of patterns sanctioned by none and perfected by necessity.

Mk VI Interdictor War-plate

Derived from the Mk X Phobos-pattern Astartes armour; this sleek, black, angularly faceted plate is lighter than traditional Sororitas armour, optimizing stealth capabilities of Dominions and Seraphim.



Mk VII Judicant War-plate —

A cousin of the iconic Terminator lineage of power armour, re-engineered for baseline humans to maximize the combat lethality of Zephyrim and Celestians while permitting Retributors to wield weapon systems previously restricted to Astartes.



Mk III Ultora Jump-pack —

Utilizing superior flight systems adapted from the Custodes Venatari chassis, featuring an unprecedented quad-wing array—four thruster vanes unfolding as mirrored pairs in cross-formed symmetry said to emulate the angelic hosts of the Imperial Creed.



Mk II Venatrix Jetbike —

Resurrecting the ancient Erinyes-pattern once fielded by the Sisters of Silence, Karytine artisans forged a fast-attack platform of extreme manoeuvrability and devastating armament, purpose-built for hunting behemoth-class threats in coordinated packs, yet still bearing the sculpted, baroque elegance of a more civilized age.



Mk I Verdalux Sensor Array —

A full-spectrum auspex suite embedded within all Verdigris-spec Sabbat-pattern helms; its optical core emits a distinct green glow—a doctrinal marker denoting the bearer operates under Oculis Imperatoris oversight.

Such fusion of technologies could not exist without the quiet indulgence of the Imperium’s highest powers. No public decree records the requisition of the Verdigris’ armament; if authorization was ever granted, it lies only in sealed communiqués between the Lord Regent, the Abbess Sanctorum, and the Captain-General—a cadre of High Lords most aligned with the Lord Regent’s Indomitus Reforms. To the wider Senatorum, this silence serves as its own confirmation: what the Lord Regent does not forbid, none dare condemn.

"Above the Emperor’s head was a ring of jump-pack warriors unlike anything I had ever seen—circling slowly, like the Emperor’s fiery halo, resplendent and terrible, pouring wrath down upon His enemies…

But it was the wings that struck me most—their flight systems bespoke, more art than engineering—symmetrical, radiant, unfurling with sacred geometry, holding them aloft in the last rays of the setting sun…

In three words, the warrior said more than hours of an iterator’s sermon. They took no accolade for themselves, instead honoring the fallen, and those who persevered. 

They knew the canticum of the sentinel, metered in darkness, and sung in silence—that benediction, not for glory, but purpose, and the victory born of sacrifice.”

Heraldry

The Tarnished Rose

The symbol of the Verdigris—called the Tarnished Rose by those few who have seen it—appears upon their armour only after the Vow is taken. Etched into bare ceramite and allowed to patinate naturally, it is composed of a five-petaled rose—angular, as if forged from steel rather than grown—encircled by a halo of directional rays: the rose for the Sisters who were broken yet endured, the rays for the Emperor’s light carried into shadow.

Unlike the ornate heraldry of the Orders Militant, the Tarnished Rose is never gilded or enameled. Its form is austere, its hue whatever green or brown the metal chooses to become. In this way, each Sister bears a sigil uniquely her own—proof that the Emperor’s chosen may tarnish, but cannot be undone.

“Let the rose tarnish—so the Imperium endures.”

—Verdigris Insignium

Notable Figures

Tribune Decian Thalor

Rising from Virtus Praetor of the Emissaries Imperatus to Shield-Captain of the Legatus Illustris during the Great Crusade, Decian Thalor became the Emperor’s most eloquent diplomat and His most ruthless spymaster. Among the Astartes Legions he was mocked as Bellator Eloquiithe Warrior of Words—for he brought countless worlds to compliance not by bolter and blade, but by oath, intrigue, and the Emperor’s subtler will.

The Master of Mankind Himself judged the truth of Thalor’s worth, bestowing upon him a name unique among all the Ten Thousand: Astutia Excelsior — Supreme in Cunning.

When the Emperor fell, Thalor entered the Long Silence, standing millennia as a mourning sentinel within the Sanctum Imperialis. In the Age of Apostasy he broke that silence, gathering the remnants of his company to fight once more as the Legatus Obscurus, shadows honed by grief and purpose renewed to see their Master’s design endure.

With the dawn of the Era Indomitus, Captain-General Trajann Valoris elevated Thalor to Custodian Tribunate, entrusting him to reconvene with the Eyes of the Emperor across a fractured Imperium. His mastery of unseen war—honed over ten thousand years—made him the natural architect of a new kind of instrument.

Thus did Thalor become the clandestine hand that shaped the Verdigris. Under his guidance, Sisters broken by trauma were not discarded but reforged—made into operatives mirroring the Custodes in miniature: autonomous, versatile, unwavering. He taught them discernment over obedience, purpose over ritual, truth over dogma.

Thalor’s legacy is not written upon banners, but upon every silent victory won before the Imperium ever learns it was threatened. The title the Emperor gave him endures not as boast, but as prophecy: Astutia Excelsior — Supreme in Cunning — who prepared His mortal daughters to carry His light into the shadows.

Canoness Grace Ferradomina

Among the Verdigris, there is no figure more whispered of—nor more fiercely revered—than Canoness Grace Ferradomina.

Once a peerless Jump Canoness of the Order of Our Martyred Lady, she was the first Sister Pilgrim to reach Holy Terra after the Siege of Ophelia VII and petition the Abbess Sanctorum to take the Vow of Verdigris.

It was upon seeing Ferradomina—already an icon of her Order—kneeling before her, surrendering her holy blade and asking to “pass into rust” that Vahl’s long-troubled prayers finally found shape. The revelation struck her like a voice not her own: these Sisters were not passed over for martyrdom, but chosen. Grace would be the first—not of an Order, but something greater.

In that moment, as legend records it, the Verdigris were born.

Grace’s keen mind, regal bearing, and striking beauty hint at a bloodline bred for greatness, but any such birthright was scoured clean by the Schola Progenium. All that remains is what the Adepta Sororitas forged from the ashes: a commander of piercing clarity, and a weapon honed not by privilege, but by choice.

Renowned for her blade-craft, she bears St. Katherine’s Mercy, a great power sword almost two meters in length. In armour she wields it one-handed, flowing through forms even in the heavy Judicant war-plate with effortless precision. Out of armour she is no less deadly, fighting with a weapon nearly matching her height, turning the massive blade with dancer’s poise, exploiting its weight, hooks, and pommel with ruthless ingenuity.

The All-Saints Day on which young Zephrym Ferradomina was entrusted with St. Katherine’s Mercy has been scrubbed from Imperial record by decree of the Order’s Canoness Superior—yet rumours endure. Witnesses tell of a ritual honour bout in which Grace crossed blades with St. Celestine herself. No reason was ever given, and no victor recorded, but all agree on one thing: the duel marked her as a woman of cold, calculating fury and flawless resolve.

Elevated to Canoness-Commander of the first Verdigris, it was Grace who shaped their earliest Maxims and laid the philosophical foundation for all that would follow. Her own transformation—from a Sister broken by the scars of youth and the trauma of war into a leader renewed by purpose—became the antidote to the death-cult fatalism that haunted her former Order. It is this conviction that defines the Verdigris: true devotion to the Master of Mankind is not proven by the ease of martyrdom, but by the unending labour of preserving His vision.

"To die for the Emperor is to lay your burden down. To live for Him is to carry it for a lifetime."

 — Canoness-Commander Ferradomina, Maxim I, Doctrine Verdigris

Dialogus Praevera Lex

Of all who have taken the Vow of Verdigris, none is more unexpected—nor more quietly extraordinary—than Dialogus Praevera Lex.

Born to minor functionaries of the Adeptus Terra and raised in the shadow of the Imperial Palace, Lex lived an unremarkable life until entering the Convent Prioris. There she served the Order Dialogus, trained in linguistics, illumination, and the labyrinthine theologies of the Ecclesiarchy. She had never borne arms, never marched with an Order Militant, and had no rightful place in the crucible of war. By every tradition, she should not even have known the Vow of Verdigris existed—yet within weeks of the first vow being spoken, Lex stood before the Abbess Sanctorum and petitioned for it.

What compelled her remains unrecorded, but those present speak of a sincerity that unsettled the chamber—the young Sister was neither bold nor fearful, only certain, with the serene conviction of one answering a summons she could not name. Moved by that uncanny resolve, Abbess Vahl granted the petition. Thus did Praevera Lex become the second Verdigris.

Her transition from scholar to warrior revealed gifts no one had anticipated. When not tempering her once-sedentary frame through Custodian regimen, she vanished into archive-vaults, consuming ancient texts and forgotten manuscripts with voracious intensity. She possessed a genius for language bordering on the miraculous: disentangling dialects thought dead since Old Night, reconstructing meaning from damaged catechisms, and unweaving cyphers that confound even the Inquisition.

Tribune Decian Thalor took particular interest in her. Walking the palace grounds in long discourse, he found that Lex perceived mechanical, mathematical, and astrological lore with an intuition that defied her training. Lacking the technical vocabulary, she expressed these insights in theological or metaphysical terms—yet the underlying logic was flawless. Thalor concluded that her mind worked in architectures of grammar and intent, perceiving design where others saw only mysticism or ornament.

Yet intellect alone does not define her. Praevera possesses a quiet radiance—an earnest gravitas disproportionate to her years—as though she moves in harmony with a truth she cannot yet articulate. Veterans of the Astra Militarum, frigid agents of the Inquisition, even gene-wrought Astartes speak of the same instinctive response: a desire to shield her, though none can say why.

In the field, Lex wears the Interdictor war-plate, its sensorium arrays and diminished signature allowing her to serve as the Verdigris’ unseen eye—interpreting signals, discerning hidden patterns, and providing insight amid the shifting chaos of war. Though new to battle, she adapts with startling speed, not through martial instinct, but because she studies combat as she studies scripture: patiently, thoroughly, with a scholar’s hunger to understand what others take for granted.

As principal author of the Doctrine Verdigris, Lex gave shape to the covenant’s soul—humble, luminous, and utterly devoted. Penned as scripture yet sharpened by reason, her treatise defined the paradox at their core: maintain absolute purity even as duty compels them to tread the very edge of heresy, all to preserve the greater unity of the Imperium.

The Verdigris endure in silence as the unknowing name them damned, while those at the tip of the Imperial spear recognize them as the temper that keeps the Emperor’s blade from breaking.

“We resonate with His will—and are remade in His image. I’m sure that once we go forth to make His will manifest, this gift shall fade. But here, now, we cast off mortal limitations—malleable as Terran clay, pure as blank parchment. He did not send such materials to the blacksmiths of the Astartes to be hammered into tools. He sent us to His artisans—His Custodes—to be sculpted with finesse.”

— Praevera Lex, in conversation with Tribune Decian Thalor

Sister Kaleith Scindor

None among the Verdigris is more fearsome—nor more marked by trial—than Sister Kaleith Scindor.

Born on the harsh agri-world of Boudica and driven by hardships recorded only as expunged by decree of the Prioress, Scindor’s earliest years remain sealed under Ecclesiarchal censor. Her life might have ended in obscurity had the Adepta Sororitas not taken her in. What the Order of the Bloody Rose found in the young girl was not piety, but fury—raw, directionless, and absolute. They gave her a place to wield it. She gave them a weapon unlike any they had ever seen.

As a Repentia Superior, she drove the condemned into the jaws of war—lash in hand, voice like iron. Her brutality became a whispered legend even among her own Order. Yet every soul she drove to repentance left a mark upon her spirit, incisions no discipline could heal. During the Siege of Ophelia VII, her convent was razed. In the end she stood alone among her slain Sisters, unable to tell if the blood upon her belonged to the pious or the penitent. When silence fell upon the battlefield, the wounds of endless cruelty finally consumed her.

Abbess Vahl keeps no records of petitioners who seek to “pass into rust,” nor the tears they weep when they are told they are not forsaken, but chosen—that a soul steeped in savagery and suffering was forged not in vain, but to serve anew. So it was with Kaleith Scindor, the third to take the Vow of Verdigris—who became the Emperor’s ruthless will given mortal form.

Within the Verdigris, Scindor remains a towering figure: broad-shouldered, severe, standing a head taller than any of her peers. Often judged callous or intimidating, it is astride the Mk II Venatrix jetbike that Kaleith becomes as she was always destined to be. The resurrected Erinyes-pattern—swift, elegant, precise—grants her a grace she had never possessed. Those who witness her in motion speak of an aerial predator—not an aquila of radiant gold, but an archangel of weathered patina—silent in her dive, devastating in her strike.

Elevated to Venatrix-Superior, Scindor became the architect of the Tripudium Venatricis—the Dance of the Huntresses—a fighting art born from her study of the Venatrix’s capabilities. It is no mere attack formation, but a choreography of coordinated lethality: six riders encircling a foe, weaving in shifting cadence, harrying from oblique angles, feinting patterns that invite misjudgment—then, at the instant the enemy believes they have discerned the rhythm, striking the killing blow. It is meticulous, merciless, and unmistakably hers.

Yet beneath her ruthlessness lies something rarer still: redemption. Among her new Sisters, Kaleith became a paragon of the Emperor’s martial virtue, tempering violence with purpose and rage with clarity. Her fury did not wane—but what was once a bludgeon of wrath became an executioner’s blade, sharpened by meaning and honed by choice.

In the annals of the Verdigris, none stands as more powerful a testament to transformation as Sister Kaleith Scindor—a devastated orphan, once hammered into a scourge of penance, reforged into the Emperor’s shield, held fast against all that would unmake His Imperium.

“Hear me, Astra Militarum…
What comes to bear threatens all Mankind. And you alone are the last line of defense.
No other Imperial force will come to save us this day.
So to the last squad, to the last man, to the last breath—
in the name of the God-Emperor, you will hold this line.”
